Installation of Tekonsha T-One Connector

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located in your rear cargo area. You will have to remove the access panel doors to access this harness. Once you've plugged in the T-connector, run the body harness up to your car battery and connect the wires per the included instructions.


Once installation is complete, the 7-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 7-pole connector itself - to help prevent corrosion.


ModuLite Powered Tail Light Converter

A ModuLite power module is built into this T-One connector. Because most trailers run on a 2-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's 3-wire system need to be combined so they are compatible with the wiring system of your trailer. This power module functions as a tail light converter to combine the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.


Installation of Tekonsha Brake Controller Adapter

This adapter plugs into the 4-pin connector on your vehicle's built-in brake control wiring harness. The harness is located near the steering column, through a grommet in the engine compartment.


This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

2016 Ram ProMaster 2500

I purchased the wiring kit, brake controller and extra bracket for my 2016 Promaster 118. The install went great. I used another stainless steel bracket to attach the 7 way to the bumper cover. It looks good and totally professional. The brake controller sits just below the fuse box and is out of the way but accessible. I did route my power wires going to the front beneath the van. I drilled a 1/2 inch hole through the rear plastic of the battery box to bring those wires in. 302796

The website is easy to look at and explains what you need to know. The delivery took some time but it was because we were waiting on one of the parts. Someone emailed me and offered a different product so that we could get our delivery faster. We didn't need the parts that fast so we just waited for the original part. Overall a great experience. 756414

YES...YES...YES...My Ram Promaster 1500 did not have factory installed Trailer light system. I contacted a nationally recognized trailer/hitch company to install my system and after 7 hours of my wasted time/money, they failed to do it correctly. I had used a similar product to this in the past and it worked well so I ordered this one as I upgraded to electronic brake controller. Came with EVERYTHING needed. Complete instructions. PERFECT PRODUCT...PLUG AND PLAY...Just make sure you order the correct one for your application (4 pin, 5 pin, 7pin) and adapters if needed. I operate in harsh environments of heat, cold, dust, off road... so I also use the dielectric grease on all connections . Wires are also protected by secondary abrasion protection outer wrap...Does not get any better than this. Dont buy cheap knock off wires at your local auto store...do it right, your pulling valuable equipment and have a responsibility to tow safely. 586086

  • Adding a 7-Way Connector and Brake Controller to a 2014 Ram ProMaster 2500
    In order to install a 7-Way trailer connector and brake controller on your 2014 Ram ProMaster 2500 you will need a couple of items. First you will need to install a wiring harness which will end up being part of the 7-Way connector installation. For that, yes, you can use # 22112 which also comes with the wiring needed to install a brake controller. The only other part you will need is the brake controller. For a brake controller I recommend the Redarc Tow-Pro Elite # 331-EBRH-ACCV2...

  • Will Trailer Connector and Hitch Work Together on 2015 Ram ProMaster 1500?
    Curt hitch # C13295 and connector # 22112 will work together just fine in your 2015 Ram ProMaster 1500. If you were speaking about the mounting of the 7-way on the hitch, then what you would want to do is use the No-Drill Bracket # 18140 and Mounting Bracket # 18138 to mount it to your hitch. I've added links to video reviews of each product for you to take a look at.

  • 7-Way Recommendation for a 2006 Dodge Ram 2500 to Bypass Factory TIPM
    I have a solution for you, but the # 22112 would not work on your 2006 Dodge Ram 2500. Instead you would need to start with the part # 118381 as a 4-way. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake controller.

It doesn't require any drilling so installing it is super simple. It's rated to tow up to 6,000 lbs and 600 lbs tongue weight. For a wiring kit that comes with everything you'll need to install a fully functional 7-way connector, the Tekonsha # 22112 is the way to go.

    The restrictions for the hitches that fit the 2017 Ram ProMaster 2500 only pertain to if it is an EXT model or not. Curt trailer hitch # C13207 does not fit the EXT models. If the step you have installed is the step bumper then there should not be a problem. If it is a side step then you will want to look over the linked instructions for the hitch to see where on the vehicle it installs and if that conflicts with where the step installs. If you do have an EXT model then the comparable...

    For the 2019 Ram ProMaster 3500 there is not a direct wiring harness. If you want to use the P3 # 90195 then you will need to use the kit # ETBC7 to hardwire it. If you don't have the factory tow package, you will also need the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118618.

  • Domestically Manufactured Hitch for 2016 Ram ProMaster 1500
    Draw-Tite manufactures their receiver hitches in Mexico. If you'd prefer something manufactured in the USA, Curt offers a similar hitch as part # C13295. If you need a trailer wiring harness but you already have the factory tow package, you'd use # HM40975 or # 22112 if your ProMaster doesn't have the tow package. For a ball mount, use # 2923 and for a 1-7/8 inch ball use # 19260 or # 63845 for a 2 inch ball. I've linked you to some installation videos that you might find helpful.
